最近几年来,焊条制造工业在我国有了很快的发展。現在我国已經可以完全应用国产原材料,运用我国自制的高压油压式压力机来制造高級的优質焊条。本文簡要的介紹一些資本主义国家已經公开的若干低碳鋼焊条配方。配方中仅列出十分近似的数值,而且原料規格方面的資料也非常缺乏,只供有关人员在研究试驗工作中参考。 In recent years, electrode manufacturing industry in our country has developed rapidly. Now China can already fully use the domestic raw materials, using our own high-pressure hydraulic press to create high-quality welding rod. This article briefly introduces some of the mild steel electrode formulations that have been published in capitalist countries. Only a very approximate numerical value is listed in the formula, and the material specifications are also very scarce. It is only for the reference of relevant personnel in the research and experimental work.
